ATTAGHIVIENT FOR WOQD -TUR-NING LATHES.

Application filed June 23, 1922. seriarmfwocea T 0 all to 7mm it may concern:

Be it known that I, J AM'ES CHADEK, a citizen of the United States, and resident of Appleton, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Attachments for food-Turning Lathes, of which the following is a specification.

The invention relates to wood turning lathes and the primary purpose of the invention is -to provide an attachment for such lathes which will permit the operator to make any number of duplicate turnings more rapidly and accurately than is now possible according to the hand turning methods in use.

Other objects of the invention, as well as the particular combination, construction and arrangement of parts will be more readily understood from the following description and accompanying drawings in which,

Fig. 1 is a fragmentary perspective view of a lathe showing my attachment in place.

Fig. 2 is a side view of the attachment of the lathe shown in Fig. 1, the templet or profile member being in section; and

Fig. 3 is a top plan view of a follower forming part of the attachment.

Referring more particularly to the drawings, 5 designates awood turning lathe of ordinary construction and 6 is a tool rest suitably secured to the lathe to extend longitudinally thereof.

The tool rest 6 is formed with a lateral shelf 7 supporting the profile member or templet 8, which is secured to the said shelf by means of screws 9 or other equivalent fastening means.

The top of the tool rest 6 is provided with a longitudinally extending guide groove 10, receiving therein a lug 11 carried by the tool guide 12 slidably supported on the upper surface of the tool rest for movement longitudinally thereof.

The tool guide 12 comprises a base plate 13 from which extends a pair of vertical walls 14 spaced apart to provide an intervening slide passage for the chisel or tool 15 which is thereby adapted for movement transversely of the tool rest.

The chisel 15 has secured thereto a suitable follower comprising a yoke 16 and an extension 17 terminating in a depending lug 18 adapted to engage and follow the de sign of the templet or profile member 8. The follower is held against movement on the chisel means of a set screw 19 passing through the yoke 16.

In the operation of this invention, the chisel 15 is held by the operator in a horizontal position and is free to move in or out through the passageway provided between the walls 14. of the guide 12 and is also free to move to either side or longitudinally of the tool rest with the said guide 12, being guided in such movement by engagement of the lug 11 in the groove 10. As will be obvious, the inward and outward movement of the chisel 15 is controlled by the engagement of the lug 18 with the templet or profile member 8.

Having thus fully described my invention, what I desire to claim by Letters Patent is:

1. The combination of a horizontally disposed profile member, a chisel guide mov-- able longitudinally of said member and provided with a chisel passage extending at right angles to the direction of movement thereof and a chisel freely movable in said passage and equipped with a follower engageable with said profile member.

2. The combination of a horizontally disposed profile member, a guide constrained to move longitudinally of said member comprising a base plate and a pair of vertical walls rising from said plate and spaced apart to define an intervening chisel passage which extends transversely with respect to the profile member, a chisel freely movable in said passage and equipped with a follower engaging and cooperating with the profile member to control the movement of the chisel in said passage.

3. The combination of a support provided in the top surface with a longitudinally extending groove, a horizontally disposed profile member carried by the support with the profile edge facing outwardly, a chisel guide comprising a base plate slidable longitudinally on the support and equipped with a depending projection operating in said groove and a pair of vertical walls rising from the base plate and spaced apart to Provide an intervening chisel passage extending transversely with respect to the support, a chisel freely movable in said passage and a follower carried by the chisel and disposed for engagement with the said profile edge to control movement of the chisel in the chisel passage.

4. The combination of a support provided in the top surface with a longitudinally exsaid support, a chisel freely slidable in said tending groove, a horizontallydisposedpropassage, a sleeve adjustahly secured on said file member carried by thesup port with the chisel and a lug carried by the sleeve and profile edge facing outwardly, a chisel guide disposed to engage the aforementioned pro- 5 comprising a base plate slidable longitudifile edge to control movement of the chisel 15 nally on the support; and equipped with a in the said chisel passage. depending guide projection operating in said In testimony whereof I hereunto affix my groove and with a pair of vertical walls signature. spaced apart to provide an intervening 10 chisel passage, extending. transversely of JAMES
